context_page_description: Corymbia calophylla is a large and common tree in the southwest of Australia.
  Originally described as a species of Eucalyptus, it was separated to a genus allied with the bloodwoods and their relations. Corymbia calophylla is commonly known as marri, a name derived from the Noongar language of Southwest Australia region, in preference to the ambiguous red gum. The trunk responds to damage by insects by exuding a red, blood-like substance, a type of kino, that is able to be collected for a variety of uses. Able to establish itself as a very large tree, the fast growing species often colonises and out-competes other woody species in disturbed areas. The large green leaves of marri will create well-shaded areas that impede other plants' growth and a create a comfortable refuge or habitat for a large number of animals. The complex fissures and bark of the trunk and branches are also utilised by a diverse array of organisms.
context_section_description: Marri is widely distributed in the Southwest region of Western Australia, from north of Geraldton (28° S) to Cape Riche (34° S), and inland beyond Narrogin (32°56′S 117° E). It is found  displaying its adaptability to the different environments on the Swan Coastal Plain and the Darling Scarp.
  Where the soil type is appropriate it will dominate as the upper storey in woodland, to within a few kilometres from the coast.
  The species will grow on comparatively poor soil, but good specimens are considered an indicator of the better agricultural soils. Found in a variety of terrains including Flats, hills,  breakaways, wetlands, fringing salt marches and beside drainage lines it is able to grow in red-brown clay loams, orange-brown sandy clays, gravel and grey sandy soils over limestone, granite or laterite.
  The marri range and population has increased and decreased with recent environmental changes, urban development, land clearing, intensive agriculture and altered fire regimes.
